Description
- The invention refers to an insulating loading bay, of the type aimed to be secured in a protruding position in respect to the front of a building and aligned with a loading bay for trucks or similar vehicles, located in an opening for the access to the building having an insulating shelter and an extension shaped as an inverted "U" for the closing of the sides and top portion of a passage area between the loading box of a truck and the opening to access to the building, as well as a moveable footbridge which communicates the floor of the building or premises with the loading box of the truck.
- This shelter has construction characteristics aimed at permitting a vertical swiveling movement of the shelter in respect to the loading box of the truck, during the operations of loading and unloading of the same, and to establish a total lower part closing to minimize the energy losses, as well as to prevent the eventual entry of insects, rodents, etc. thanks to a flexible lateral closing established between the footbridge and the interior sides of the insulating shelter and said extension.
- This invention is to be applied to loading bays of buildings, mainly air conditioned buildings, with the aim to minimize the energy losses during the processes of loading and unloading of the trucks.
- Currently, the air conditioned premises have insulating shelters permitting to minimize in a higher or lower degree the energy losses in the processes of loading/unloading the trucks.
- These insulating shelters are located in the front part of the opening for the door of the loading bay and, for being fixed, the vertical oscillations of the truck during the process of loading and unloading, provoke an early wear of the same.
- Generally these shelters are prepared to receive a controlled pressure on occasion of the trucks going back towards the loading opening.
- One of the most important shortcomings in this type of installations is that of not having solved the lower closing of the shelter through which an important part of the air conditioning of the installation is lost, being as well a point of entry for insects, rodents, etc. This area is presently occupied by a hydraulic ramp or footbridge, permitting to communicate the premises with the truck.
